More info

Molybdenum-copper (MoCu) alloy features an adjustable thermal expansion coefficient and thermal conductivity. The molybdenum to copper ratio is customizable, offering lower density but a higher thermal expansion coefficient than tungsten-copper (WCu) alloy. Its superior rollability makes it suitable for thin strip production and stamping, enabling cost-effective, high-volume production of heat-sinkable parts. Consequently, MoCu alloy is more suited for aerospace and other industries.
